Claims.

This invention relates to closure assemblies for ventilating areas in windows and in more particular to ventilating areas in metallic windows.

"An object of this invention is to provide a 5 closure assembly for windows wherein the guards across the window opening have been incorporated into the window structure.

Another object of this invention is to provide a closure provided with a flexible contact engago-ing the frame surrounding the closure.

Another object of this invention is to provide a closure'for a ventilating area that is of less width than the distance between adjacent muntin bars. I

Another object of this invention is to provide a'closure for ventilating areas or windows that is cheap, emcient, durable and dependable, that makes good contact so as to protect the interior of the building from the elements.

Another object of this invention is to provide a unitary structure for the closure and its screen thatmay be inserted as a unit into the ventilating area; g g

With' the above primary and other incidental 5objects in view, as will more fully appear in the specification, the invention consists of the featuresof construction, the parts and combinations thereof, and the mode of operation or their equivalents, as hereinafter described and set forth in the claims.

Fig. 7 is a sectional View taken substantially onthe line 'l-'l of Fig. 6. I I I *Fig. 8 shows a vertical sectional view of another modification.

Fig. 9 shows aperspective view of a modification similar to thatshown in Fig. l with the closure' removed. i a so 1 Referring to the drawings the modification disclosed in Figs. 1, 2 and 3 utilize T-shaped muntin bars 20 transversely arranged, dividing the window into a plurality ofspacessome ofwhich are glazed as showniiat 22, leaving a groupof spaces 3 5 vacant either entirely across from one muntin bar tect the occupants of the building during inclemd ent'weather, it is desirable to provide a suitable closure for this ventilating area.

In the preferred embodiment, as shown in Figs. 2 and 3, the closure assembly including the frame 24 supporting the screen 26 upon one side and the sheet metal closure 28 upon the same side, is inserted as a unit into the ventilating area 23. The space 26 intermediate the muntin bars 20 and the frame 24 is preferably filled by a pliable, plastic or yieldable material, as the case may be. In the present embodiment putty or cement has been shown. In the preferred embodiment the sheet metal closure 28 has been hinged at 30 and is biased into open position by a fiat spring 32 normally holding the closure open. Resilient members 36 act as weather stripping between the closure 28 and the fixed parts bounding the ventilating area. The frame 24 is attached to member it] best seen in Fig. 3, that is provided with a flange 38 against whichthe glazing 40 is mounted. The stem of the muntin bar Zita is preferably provided with a saw-cut to receive the frame 24. By releasing the closure chain 34 the closure 28 springs into open position under the influ- 30 once of the spring 32. Whenever it is desirable to close the ventilating area this may be accomplished by pulling the chain 34, which may be held in closed position against the force of the spring 32 by a suitable latch not shown or by 3 any other suitable s-ecurement of the chain.

. In the modification disclosed in Figs. 4 and 5 another type of metallic closure has been shown, wherein the closure is located along the confines of the muntin bars. This modification includes a U-shaped portion 4|, extending along two sides of the window, arranged to hold the felt 42 or other yieldable material contacting the flanges 44 of the muntin bars 29 bounding the ventilating area. This U-shaped member 4| is comparatively rigid and forms a frame reinforcing the sheet metal closure it. In the modification disclosed, the sheet metal closure is integral with the U-shaped member M. It may be attached thereto by welding or in any other suitable manner. I

As best seen in Fig.4 the top and bottom edges of the closure 46 are formed into U-shaped portions. The vertical side portions are bent into U-shape arranged in hooked relation with the 5 flexible Weatherstripping members 55 formed from suitable resilient metallic strips. As the 010- sure abuts the inside of the flanges t4- and lies substantially within the confines of the T-bars, it is not feasible to continue the muntin bars across the ventilating area. That being the case, suitable bars extend across the ventilating area and are substantially aligned with the flanges id of the T-bars. These detentionbars 38 which prevent the free ingress and'egress of human bodies through the window, may be aligned with the flanges of the T-bars, so as to simulate a window wherein the T-bars extend across the ventilating area. These guard bars or detention bars 4.8 may either be attached to the transversely arranged muntin bars bounding the ventilating area, or the detention bars 46 may be secured to the screen frame is located on the side of the flanges Q4 opposite the closure member iii. The screen frame may be held in position by any suitable means. In the modification disclosed, the screen frame has been soldered to the flanges t4.

In the modification disclosed in Figs. 6 and 7, U-shaped channels supporting the felt d2 instead of being made from a unitary member is shown in the previous modification, is made from a pair of flanged members 58 and 62. The opposite ends of members Gil and 62 form another U-shaped channel {i l receiving the glazing 5d. The flanges form.- ing the Ushaped channel 66 extend in a direction parallel to the plane of the glazing 58 in contrast to the legs of the channel supporting the felt 32, which legs extend in a direction normal to the plane of the glazing The closure assembly is pivotally mounted on a pair of pintles 3b supported in member '16 overlapping the fianges id and attached thereto by welding or in any other suitable manner. Referring to Fig. 6 member iii also forms the sill for the closure as a portion is overlaps the flange of the muntin extending along the bottom of the closure. Suitable bolts 32 passing through the web of the muntin bar may be tightened to hold portion it in engagement with the web of the muntin bar. Instead of bolts, these parts may be welded together into a unitary structure.

In this modification a screen t l is positioned intermediate the closure and the muntin bars of the window. The portion $6 of the screen extending along the bottom thereof forms an abutment for the weather-stripping 42, so as to provide a seal above the sill. The sill of the window in this modification prevents the closure coming in contact with the flange of the muntin bar extending along the bottom of the closure.

Referring to the modification shown in Figs. 8 and 9, the screen frame assembly projects through the ventilating area. The screen frame W is formed from angle bars having the flanges 92 projecting through the ventilating area and supporting the screen 9 8 suitably attached thereto. An abutment or snubber 96 attached to the lower flange 32 holds the screen frame at a proper height. A stop Q'l is arranged in hooked relation with the flange M to prevent the screen frame from removal bodily inwardly when the upper flange is held in position by a diagonally arranged screw 98.

The closure ltd pivotally attached by hinges E62, only one of which is shown, to the web of the muntin bar 2t extending along the bottom of the ventilating area, is held in closed position by a suitable latch arrangement liifl in a manner similar to that shown in the other modifications.

The flanges W6 of the screen frame are arranged in spaced relation from the flanges it of the muntin bars. Weatherstripping members H0, substantially U-shaped in cross sectional area, are arranged in hooked relation with the flanges 8%. One leg of each Weatherstripping member Eiii abuts the flange 44 and the other abuts the closure when in'closed position. The Weatherstripping. members i i ii are duo-functional in that in addition to providing weather tightness, these members provide a cushioned support for the screen frame. This assembly provides a very satisfactory closure assembly mountable into any space left vacant for ventilating area without the use of accurately milled parts, as the clearances may be sufficiently great to allow for almost unlimited tolerances in workmanship.

In the modification disclosed in Fig. 9, the metallic closure 28 has been removed. As may be clearly seen, the hooked shape edge I28 may be hooked under hooked. shaped stationary member I22 rigidly attached to the frame of the window.

From the above description it will be apparent that there is thus provided a device of the character described possessing the particular features of advantage before enumerated as desirable, but which obviously is susceptible of modification in its form, proportions, detail construction and arrangement of parts without departing from the principle involved or sacrificing any of its advantages.

While in order to comply with the statute, the invention has been'described in language more or less specific as to structural features, it is to be understood that the invention is not limited to the specific features shown, but that the means and construction herein disclosed comprise the preferred form of several modes of'putting the invention into effect, and the invention is therefore claimed in any of its forms or modifications within the legitimate and valid scope of the appended claims. a
